To evaluate the reliability of manual tracings compared to specific softwares for this purpose, the sample was composed of 45 lateral cephalograms (Figure 1) of individuals submitted to orthodontic treatment. This study aimed to evaluate the reliability of manual cephalometrics compared to two specific softwares and quantified the degree of reliability of identification of cephalometric points manually and digitally, evaluating and comparing the outcomes achieved and comparing them to each other, to aid the clinician in selecting the best option for cephalometrics, either manual or computerized. This study aimed to compare the error in cephalometric measurements with manual and computerized methods using the softwares Dolphin Imaging and Dentofacial Planner, aiming to evaluate the reliability of cephalometrics techniques analyzed. Several systems and formats are available to produce, store, recover, visualize and share these images. Digital images are currently routinely used in the orthodontic practice. The constant technological advances in the field of computing, combined to scientific advances in dental radiology, led to the development of computerized softwares for cephalometric tracings and measurements, as well as accomplishment of different types of analysis. With the increasing presence of informatics in the clinical routine, it has been a great aid to speed up the work, optimize tasks, simplify procedures and increase the productivity and refinement of diagnosis. The radiographs must be technically perfect, without distortions, to allow good visualization of bony anatomical structures and the soft tissue profile. #Dolphin imaging how toįor cephalometric analysis, it is necessary to accurately define how to identify the different specific points used. įor a long time, manual tracing was the only method available for cephalometric tracing and achievement of angular and linear measurements required for interpretation. Since 1931, bidimensional images have been used to identify the anatomical landmarks with which the cephalometric measurements are obtained. The radiographic image is an important aid in the diagnosis and evaluation of skeletal and dental relationships. Since the advent of the first dental X-ray machine in 1919, radiographies have been used for several purposes, including diagnosis, evaluation of pathologies, periapical lesions, tooth resorptions and evaluation of existing endodontic and restorative treatments.Ĭephalometrics appeared as an evolution of craniometry from the standardization o radiographic techniques and development of the cephalostat proposed by Broadbent in 1931. #Dolphin imaging softwareThe computerized method using the Dentofacial Planner software showed the highest reliability, followed by the manual method, while the Dolphin Imaging software was the least effective and more likely to produce systematic errors in the identification of points. Results: The results showed statistically significant differences, especially between measurements evaluated on the Dolphin software and by manual tracing (p>0.05).Ĭonclusions: According to the present results, the three cephalometric methods have proven to be accurate, since they presented few systematic errors. For analysis of results, the dependent t test was used to compare the error of each method (intragroup error) comparison of measurements between the three methods was performed by the one-way ANOVA and Tukey test in the presence of significant result. A calibrated operator conducted 90 manual and 180 digital cephalometric tracings, using 8 angular measurements (SNA, SNB, ANB, FMA, 1.NA, 1.NB, SN-Occlusal, SN-GoGn) and 5 linear measurements (1-NA, 1-NB, Co-Gn, Co-A e LAFH). Methods: The sample comprised 45 lateral cephalograms. Objective: To evaluate and compare the error in cephalometric measurements by manual and computerized methods using the softwares Dolphin Imaging version 11.0 and Dentofacial Planner version 7.02.
